Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to, for example, soil, sand,
The present invention relates to a vertical tamping device that mixes waste materials such as ash, newsprint, PET bottles, glass fibers, waste cloth, glass, wood chips, glue and the like with cement and the like, and adds water to crush and solidify.

[0002]

2. Description of the Related Art In recent years, industrial waste discharged from various industries, excavated waste, newsprint, PET
The treatment of bottles and the like is a problem, but such a method of treating waste materials is treated according to the type of each waste material.

[0003] For example, garbage from homes is mixed with other soil, decomposed by microorganisms, and returned to the soil. Discharged soil is removed by pressurizing to remove water, solidifying, and then disposed of. In particular, waste materials that do not contain water are mixed as ash after incineration or directly into concrete, dried, solidified, and blocked.

[0004] Among such methods, in the case of a work containing moisture such as the above-mentioned garbage, the work is simply pressurized by a hydraulic device or the like to remove moisture or air contained in the work. The volume can be greatly reduced and the solidified product (commonly called a dewatered cake) can be disposed of by burying it in the soil.

[0005]

However, when the soil is solidified, simply pressing it with a hydraulic device in the container cannot sufficiently squeeze the soil, and it must be pressed for a long time. There is a problem that a large amount of processing cannot be performed within a short time.

[0006] In addition, since waste materials such as newspapers and PET bottles which do not contain moisture such as PET bottles cannot be solidified by themselves, they are usually mixed into concrete containing a large amount of water exceeding 40% and mixed. After that, it is put in a predetermined mold and dried and solidified, and the ash after incineration of these is also mixed with concrete with a large amount of water, mixed, put in a predetermined mold and dried and solidified. However, this method also has a disadvantage that it takes a long time to dry and solidify, and it is difficult to perform a rapid treatment.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems associated with the prior art, and provides a vertical tamping apparatus capable of quickly and firmly tamping without using a large amount of water. With the goal.

[0008]

A vertical tamping apparatus according to the present invention achieves the above object by the following constitution.

(1) In a tamping apparatus in which a tamping material put in a container having an open top is pressed while applying vibration, an upper pressing plate for directly pressing the tamping material in the container. An upper vibrating device having an upper vibrating device for applying vertical vibration to the upper pressing plate, an upper vibrating pressing device having an upper pressing device for applying a pressing force to the upper pressing plate, and a lower portion supporting the container and pushing up the container upward A pressure plate, a lower vibration device for applying vertical vibration to the lower pressure plate, and a lower vibration pressure device having a lower pressure device for applying pressure to the lower pressure plate; It is characterized in that it is housed in a closed frame and is moved up and down along the frame by the upper and lower pressing means.

[0010] According to this structure, the tamped material put into the container is pressed while applying vibration from above and below, so that the tamped material is swiftly and extremely strongly pressed with uniform hardness throughout the container. The compacted, small amount of moisture can compress and solidify the entire particle of the compacted material.

Further, if the two vibration pressurizing means are housed in a closed frame, the amount of noise leaking to the outside can be reduced. The source can be shared, which is advantageous in cost.

(2) The container is preferably held by a side pressing plate that presses the opposing side walls from the outer periphery.

[0013] According to this structure, the pressure resistance of the container is extremely improved, and even if the material in the container is pressed from above and below, the container can be compacted with a strong force without being deformed.

(3) The frame includes a substantially hermetic main frame in which the two vibration pressurizing means move up and down, and a substantially hermetic external frame provided to cover the main frame from the outside. The main frame is held to the outer frame via a first elastic member, and the outer frame is positioned relative to a fixed body such as the ground.
It is preferable to be held via a vibration damper having a vibration absorbing function.

According to this structure, the main frame and the outer frame cover both the vibration pressurizing means, so that the noise generated when the compacted material is compacted in the container is leaked to the outside. The compacting operation can be performed quietly, and the vibration of the main frame itself is also absorbed by the first elastic member, and is not transmitted to the external frame, and the vibration of the external frame itself is also reduced. It is absorbed by the damping part and does not transmit to the ground etc.
Quiet driving becomes possible.

(4) The vibration damper is formed on the second elastic member for elastically supporting the outer frame, a bulkhead member for covering an outer periphery of a lower portion of the outer frame, and the position fixing body. It is preferable to have a water tank part filled with water in the recess, and a third elastic member provided at the bottom of the water tank part and elastically supporting the bulkhead member.

With this structure, in addition to the vibration absorbing function, a large vibration is absorbed by the second elastic member, the bulkhead member itself, and the third elastic member. The fine vibration transmitted to the water tank is absorbed by the water stretched in the water tank section, so that the vibration absorbing function is further enhanced, and the quiet operation can be generally performed by the vibration absorbing function.

(5) The vibration device has a frequency of 20 to 6
0 Hz, more preferably 40-50 Hz, with an amplitude of 0.
It is preferable to apply an ultra-high frequency vibration of 01 to 5 mm, more preferably 0.5 to 1.5 mm, to the tamping material.

In this way, the fine particles in the material enter the gaps between the fine particles and the water also enters the fine particles, so that compaction can be performed in a short time without using a large amount of water.

(6) It is preferable that the volume ratio of cement, waste material, and water, which is the tamping material, is about 1: 3: 1.

In this way, the whole particles can be compressed and solidified even with a small amount of water, and can be immediately used as a product without drying.

Is a diagram showing a state of force transmission during vibration pressurization, (a) is an explanatory diagram showing a state of force transmission by vibration pressurization from one direction,
(B) is an explanatory view showing a state of transmission of a force by vibrating pressure from both upper and lower directions.

The vertical tamping device according to the present embodiment comprises:
As shown in FIGS. 1 to 3, the frame 10, an upper vibration pressurizing unit 20 a provided in the frame 10, a lower vibration pressurizing unit 20 b, (Cart) 40 into which the compacted material W is put
And a vibration damping unit 50 having a function of absorbing the vibration of the frame 10.

The frame 10 has a main frame 10a made of an iron plate or the like having a substantially horizontal structure and a rectangular horizontal section, and a substantially hermetic structure provided to cover the outside of the main frame 10a. And an outer frame 10b made of an iron plate or the like having a rectangular horizontal section.

The main frame 10a is held by a plurality of first elastic members 11 with respect to the outer frame 10b.
Guide posts 12a and 12b (see FIG. 3) each having a rectangular cross section are provided at the corners of a and 10b, respectively, and guide means G is provided between the corners of the guide posts 12a and 12b.

The guide means G is provided with two frames 10a, 10b.
Are held so as to be separated from each other by a predetermined distance, and any frame may be used as long as one frame is configured to be able to slide smoothly with respect to the other frame. In the present embodiment, a guide roller is used. However, not only this but a polytetrafluoroethylene resin (trade name, Teflon resin) may be used.

The first elastic member 11 is constituted by a spring interposed between projecting pieces 15 and 15 projecting horizontally from the outer surface 13 of the main frame 10a and the inner surface 14 of the outer frame 10b. Have been.

In particular, the first elastic member 11 of the present embodiment
Is composed of a large-diameter spring 11a and a small-diameter spring 11b. Normally, when the wire diameter and the torsion pitch of the spring are the same, the large-diameter spring 11a has a high cushioning property but a low repulsive force, and the small-diameter spring 11b has a low cushioning property but a strong repulsive force. Therefore, both are used in combination so that both the cushioning property and the resilience are excellent.

In this embodiment, the frame 10 is composed of the main frame 10a and one outer frame 10b. However, in some cases, the outer frame 10b is only one. There is no limitation, and a plurality of outer frames 10b may be used. Further, the first elastic member 11 is not necessarily limited to only a spring, but may be any material having elasticity such as rubber or synthetic rubber.

Since the upper vibration pressurizing means 20a and the lower vibration pressurizing means 20b provided in the main frame 10a have substantially the same configuration, the upper vibration pressurizing means 20a will be described. As for the pressurizing means 20b, "b" is used instead of the suffix "a" used for the upper vibration pressurizing means 20a in the drawing, and the description is omitted.

The upper vibration pressurizing means 20a includes an upper pressurizing plate 21a for directly abutting against and pressing the tamped material W in the container 40 described later, an upper vibrating device 22a for applying vertical vibration to the upper pressurizing plate 21a, and An upper pressurizing unit 23a for applying a pressing force to the upper pressurizing plate 21a is mounted on a bottomed cylindrical frame 24a having a rectangular horizontal cross section.

The aforementioned guide means G is also provided between the outer side surface 25a of the frame 24a and the inner side surface 16 of the main frame 10a, and the bottom 27a of the frame 24a and the ceiling of the main frame 10a. The upper pressing means 23a composed of four pressing cylinders is provided between the upper pressing means 23a and the upper pressing means 23a.

The upper pressurizing means 23a is a lifting drive source which moves up and down the entire upper vibration pressurizing means 20a along the inner side surface 16 of the main frame 10a, and the upper pressurizing plate 21a presses the compacted material W. Although it is a hydraulic cylinder that is also a pressure driving source, it may be a pneumatic cylinder or the like in some cases.

In the central recess 29a of the frame 24a,
An upper vibration device 22a and a shaft 30a suspended from the upper vibration device 22a are provided.
The upper pressurizing plate 21a is attached to the lower end of a, and this pressurizing plate 21a hangs down and enters the container body 41,
The tamping material W inserted into the inside is pressurized while being vibrated.

The shock transmitted between the upper vibrating device 22a and the frame 24a during the compacting operation and the reaction force from the compacting material W cause a shock between the upper vibrating device 22a and the frame 24a. A vibration absorbing member 31a made of rubber or the like that absorbs the vibration is provided.

The upper vibration device 22a may be of any type, such as an electric type or a hydraulic type, but preferably has a frequency of 20 to 60 Hz, more preferably 40 to 50 Hz, and an amplitude of 0 to 50 Hz. It is preferable to have an ultrahigh frequency vibration of 0.01 to 5 mm, more preferably 0.02 to 2 mm. When such ultra-high frequency vibration is applied to the tamping material W, the fine particles in the material W enter the gaps between the fine particles, the volume of the entire material W is reduced, and extremely smooth tamping can be performed.

As a specific example of the electric vibration device, one shown in FIG. 4 is preferably used. The electric vibration device 22 a has a fixed eccentric weight 36 and an adjusted eccentric weight 37 attached to an end of a rotating shaft 35 provided in a case 34 of a motor 33, and the eccentric weights 36 and 37 are driven by driving the motor 33. Rotates eccentrically, and the vibration of the case 34 itself caused by the eccentric rotation is transmitted to the shaft 30a.

The container (cart) 40 has a roller 42 attached to the bottom surface of an iron plate-made container body 41 having an open upper portion, and an inlet 43 and an outlet 44 formed in the main frame 10a and the outer frame 10b. It rolls along the rail R extended to (see FIG. 2), and is carried in and out. However, the container (trolley) 40 is the lower vibration pressurizing means 2
When it is carried into the position of 0b on the pressure plate 21b, it is stopped by a stopper or a limit switch (not shown).

The container body 41 is supported from below by the pressurizing plate 21b of the lower vibration pressurizing means 20b, and the pressing force or vibration of the lower vibration pressurizing means 20b is applied to the material W in the container main body 41. The pressure plate 21b of the lower vibration pressure means 20b is efficiently transmitted.
Rises so as to avoid the rollers 42 and the rails R, and supports the bottom surface of the container body 41.

Particularly, in this embodiment, the container body 4
1, the left and right side plates 45a of the container body 41 facing each other.
Are held by a side pressing plate 46a that presses from the outside, and the front and rear side plates 45b are pressed and held from the outside by a side pressing plate 46b hinged to an end of the side pressing plate 46a. Has become.

However, these both side pressing plates 46a, 46
b is connected to the outer frame 1 via the first hydraulic cylinder S1.
0b.

The side pressing plate 46b presses and holds the front and rear side plates 45b of the container main body 41 by the side pressing plate 4b.
The operation is performed by a second hydraulic cylinder S2 mounted on 6a and a link mechanism L operated by using the second hydraulic cylinder S2 as a drive source. This link mechanism L comprises a restraining chain portion L1 attached to the side pressing plate 46b, and a pair of rotating links L2 and L3 driven by the hydraulic cylinder S2. The side pressing plate 46b of the chain portion L1 is rotated by the rotation links L2 and L3 so as to cover the front and rear side plates 45b from the outside.
By pressing the side plate 45b with 6b, the side plate 45b is prevented from expanding outward and deforming.

As a result, the container main body 41 itself does not need to have an extremely high pressure resistance. Even if it is relatively thin, the pressure resistance is extremely improved, and the material W in the container main body 41 can be removed from above and below. Even if it is pressurized, the container main body 41 can withstand strong compaction without being deformed.

However, when the truck 40 is carried out of the outer frame body 10b, the container body 41 is formed so that the crushed material W in the truck 40 can be easily taken out.
The side plates 45a and 45b may be hinged to the bottom plate so as to be easily opened.

With only the main frame 10a and the outer frame 10b, the vibration of the frame 10 may be directly transmitted to the position fixing body E such as the ground. A vibration damper 50 having a function of absorbing vibration is provided.

The vibration damping section 50 includes a plurality of second elastic members 51 around the outer frame 10b for elastically supporting the outer frame 10b so as to absorb the vibration of the outer frame 10b.
A bulkhead member 52 covering the outer periphery of the lower part, and a water tank part 53 filled with water in a recess formed in the position fixing body E.
A third elastic member 54 provided on the bottom 53 a of the water tank 53 to elastically support the bulkhead member 52.
However, also in this case, the above-described guide means G is provided between the outer frame 10b and the bulkhead member 52.

The second elastic members 51 are interposed between the projecting pieces 56, 56 projecting horizontally at four places from the outer surface 17 of the outer frame 10 b and the inner surface 55 of the bulkhead member 52.
The outer frame 10b is made of a spring 57 or rubber or the like.
In order not to transmit vibration or the like to the bulkhead member 52,
The outer frame 10b is suspended inside the bulkhead member 52.

Here, the bulkhead member 52 is a so-called damping steel plate in which an elastic member 52a such as rubber is sandwiched by an iron plate 52b.

As a result of this construction, the second elastic member 5
1, the bulkhead member 52 itself, and the third elastic member 54
Thus, the vibration is absorbed.

In general, fine vibration cannot be removed by the vibration absorbing means using a spring, rubber, or the like as described above. In the present embodiment, however, the water tank 53 is used to remove the fine vibration. Is provided. The water stretched in the water tank portion 53 has little effect on large vibrations, but exhibits a remarkable vibration absorbing effect on minute vibrations. To be transmitted to the user. As a result, the vibration absorption function becomes extremely high as a whole, and a quiet compaction operation becomes possible.

Next, the operation of the above embodiment will be described.

The truck 40 into which the tamping material W has been loaded is carried into the main frame 10a, and is set on the lower pressing plate 31b of the lower vibration pressing means 20b.

Then, the upper vibration device 22a and the upper pressure device 23a of the upper vibration pressure device 20a are driven to lower the upper pressure plate 21a while vibrating. In this case, both the vibration pressure devices 20a and 20b Although they may be driven almost simultaneously, if the tamping material W put into the carriage 40 is relatively soft, only the upper vibration pressurizing means 20a is operated until it is tamped to some extent. Is also good.

Further, as shown in FIG.
The stroke of “a” may be longer than the stroke of the lower pressurizing means 23b, and the lower vibration pressurizing means 20b may start operating after the upper pressurizing plate 21a has descended by a predetermined stroke.

However, in any case, in order to compact efficiently, as described later, the final compaction is performed simultaneously with the two vibration pressurizing means 20a and 20b.

At the same time as the start of the vibration pressing, the side pressing plate 4
6a and 46b press and hold the side plates 45a and 45b of the container body 41 from the outside by the action of the cylinder S.

As a result, the container body 41 is
The force applied to the side plates 45a, 45b is
46b will support the side plates 45a, 45b.
Even if is relatively thin, the pressure resistance is extremely improved, the container body 41 is not deformed, and the carriage 40 itself can be reduced in weight.

At the beginning of the vibration pressurization, the ultra-high frequency vibration is applied to the compaction material W, and the fine particles in the material W enter the gap between the fine particles, and the material W in the container body 41
The volume decreases at amazing speed.

After a while, the upper vibration pressing means 20
a and both pressure plates 21a, 21b of the lower vibration pressure means 20b
Is transmitted to the material W. Note that shocks and vibrations due to a reaction force or the like from the compaction material W during vibration pressurization are absorbed by the vibration absorbing member 31a of the shaft 30a.

Here, for example, with the container body 41 being filled with the material W exactly, the upper pressing plate 21a
Considering the case where vibration pressure is applied to the material W only by itself, the force applied intermittently from above is transmitted to the material W in a downward divergent manner as shown by a solid line in FIG. Then, it turned out to be horizontal at the lower part of the container body 41, transmitted to the corner, and squeezed the material W within the range surrounded by broken lines A, A in the figure.

Therefore, even if vibration is applied to the material W by only one of the upper and lower pressing plates, the compaction of the material W at the corner of the portion hit by the pressing plate is relatively weak.

The present inventor also conducted an experiment in which the material shown in FIG. According to this experiment, it was found that only the lower front portion of the container body 41 was firmly squeezed. That is, in a state where the material W is filled in the container body 41, the material W
The material W in the container is insufficiently compacted, even if the vibration pressure is applied to the material W and the force is applied from one side and the material W is placed horizontally and the vibration pressure is applied to the material W from both sides. It means that it becomes.

For this reason, in the present invention, the compaction is performed in the vertical direction from the top and the bottom, so that the compaction can be made more firmly over the entire inside of the container.

That is, the upper pressing plate 21a and the lower pressing plate 2
When vibration pressure is applied to the material W by 1b, FIG.
As shown in the figure, the force from above (indicated by the broken line in the figure) is transmitted to the material W in a downward divergent manner to the container body 4.
1, the material W in the area surrounded by the broken lines A, A is compacted, and the force from below is applied to the material W by the lower pressing plate 21b (the dashed line in the figure). ) Is added to the material W in a divergent upward direction, becomes horizontal at the upper part of the container body 41, and reaches the corner of the container body 41, and is indicated by a dashed line B,
The material W in the range indicated by B is compacted.

In this case, in the final compaction stage, the moving speed of the two pressing plates 21a and 21b is reduced. However, when the pressure is further increased while vibrating at this stage, the whole particles are compressed and solidified by the supplied moisture. The material W in the container body 41 is sufficiently squeezed from corner to corner, and has substantially uniform strength throughout.

The material W thus compacted is
It is carried out together with the carriage 40 and taken out of the carriage 40.

Next, the vibration generated by the vibration pressurizing means 20a, 20b is transmitted to the main frame 10a via the frames 24a, 24b and the guide roller G. The vibration of the main frame 10a is It is absorbed by the first elastic member 11 having both excellent cushioning properties and resilience.

However, there is a possibility that the vibration of the container (cart) 40 is directly transmitted to the outer frame 10b through the side pressing plates 46a and 46b and the cylinder 47. Is absorbed by the second elastic member 51.

As described above, the vibration of the outer frame 10b is
Although it is considerably reduced, furthermore, in the present embodiment, the vibration is significantly reduced also in this embodiment since the vibration damping portion 50 supports the outer frame 10b.

The fine vibrations remaining to some extent leak to the outside via the bulkhead member 52, but the fine vibrations are absorbed by the water in the water tank 53, and are almost completely absorbed by the position fixing body E such as the ground. It will not be transmitted. In particular, it is difficult to absorb fine vibrations by an elastic body or the like, but the water in the water tank 53 absorbs the water very efficiently, and there is almost no possibility that the water leaks to the external position fixing body E.

On the other hand, regarding the noise generated by the vibration pressure means 20a and 20b, the vibration pressure means 2
Since the whole Oa and 20b are sealed by the substantially closed main frame 10a and outer frame 10b, the amount of noise leaking to the outside is reduced.

However, since the entrances and exits 43 and 44 are opened, there is a possibility that noise may leak to the outside from the entrances and exits. If necessary, the entrances and exits 43 and 44 may be provided with doors.

Although the above is a preferred embodiment of the present invention, the present invention is not limited to this embodiment alone, and various modifications can be made within the scope of the claims. For example, in the above-described embodiment, the pressing plates 21a, 21a of the upper vibration pressing unit 20a and the lower vibration pressing unit 20b
1b is only one, but depending on the case, as shown in FIG. 7, a plurality of upper pressure plates 21a and 21b may be used.

FIG. 7 is a schematic sectional view of the entire vertical tamping apparatus according to the second embodiment of the present invention, wherein members common to those shown in FIGS. And the description is omitted.

In the vertical tamping apparatus according to the second embodiment, since the number of the upper pressing plates 21a is plural, the tamping is performed more completely than in the first embodiment, and the material W And the quality of the work after tamping is further improved.

For example, when the work after compaction is used as a material for laying a road, a more compacted work can be used, so that a good work can be obtained.

Moreover, the large number of upper pressure plates 21
When a is used, a large amount of material can be processed at once, so that the processing capacity is increased and the processing can be performed quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As a tamping material W, cement, waste material (one or more of newsprint, PET, glass fiber, waste, glass, wood chips, glue, etc.) and water are mixed in a volume ratio of 1: 3: 1. And put into a container and mixed with a mixer.

Here, the proportion of water is about 20%, which is much smaller than that of a normal one (about 40%).

The volume of the container is 360 mm × 360 mm ×
The thing of 360 mm was used. The pressure by the pressurizing means is 40 t / cm2, and the amplitude of both vibrating means is 0.5 to
1.5 mm, the frequency was 40-50 Hz, and the vibration pressure was applied for several seconds. As a result, the volume of the work in the container was 3 mm.
It was 60 mm × 360 mm × 40 mm. Water did not leak outside. This is presumably because water was used up as a binder between particles constituting the cement and the waste material, and the whole particles could be compressed and solidified.

The whole work had a uniform hardness that could be used immediately as a road laying plate without drying.

The work was submerged in water and left for several days, but no change was observed.

[0083]

As described above, the present invention has the following effects.

(1) Since the tamped material put into the container is pressurized while applying vibration from above and below, the tamped material can be quickly squeezed with uniform hardness over the entire container even with a small amount of moisture. .

Further, since the two vibration pressurizing means are housed in a closed frame, the amount of noise leaking to the outside is reduced, and the vibration pressurizing means is moved up and down along the frame by using the upper and lower pressurizing means. Thus, the drive source can be shared, which is advantageous in cost.

(2) Since the side wall of the container is held by the side pressure plate, the pressure resistance of the container is significantly improved, the container can be strongly compacted, and the weight of the truck itself can be reduced.

(3) The substantially closed main frame and the substantially closed outer frame are held via a first elastic member, and the outer frame is held on the ground or the like via a vibration damper. Therefore, the leakage of noise generated at the time of compacting is small, compacting work can be performed quietly, and vibration isolating performance is high.

(4) Since the outer frame is elastically supported and the lower part is covered with a bulkhead member and immersed in a water tank, not only large vibrations but also small vibrations are absorbed, and the vibration absorbing function is further enhanced. Quiet driving becomes possible.

(5) Since the compaction is performed by extremely minute vibration, the fine particles in the material enter the gaps between the fine particles and smooth compaction can be performed in a very short time.

(6) Even if the amount of water to be added to the tamping material is extremely small, the tamping can be performed with a considerably strong force by vibration and pressure.
